Delphi Series F48SA, 700W Full Brick Family
DC/DC Power Module: 48Vin, 28Vout www.DataSheet4U.com
The Delphi Series F48SA, 48V input, single output, full brick sized
isolated DC/DC converter is the latest offering from a world leader in
power systems technology and manufacturing Delta Electronics,
Inc. The Delphi F48SA series provides up to 700 watts of power or
up to 25A of output current. This product family operates from a wide
input range of 36V to 75V. With creative design technology and
optimization of component placement, these converters possess
outstanding electrical and thermal performance, as well as extremely
high reliability under highly stressful operating conditions. All models
are protected from abnormal input/output voltage and current
conditions, and feature 2250V input/output isolation and basic
insulation. An optional heatsink is available for extended operation.

aluminum, 1µF ceramic capacitor and 10µFlow ESR capacitor.
Bandwidth: 20 MHz. Scope measurement should be made
using a BNC cable (length shorter than 20 inches). Position the
load between 51 mm to 76 mm (2 inches to 3 inches) from the
module.
